Keratoconus treatment in McKinney before transplant is the only word on the table.
If you have been told a corneal transplant is where this ends, it is worth knowing what sits between here and there. CTAK adds tissue to reshape your cornea instead of replacing it — twenty minutes south, with the mapping to tell you honestly whether it fits.
01/Why McKinney patients come for a second opinion
“Eventually you will need a transplant.” That sentence deserves a second look.
It is the sentence that sends most people searching. Sometimes it is accurate — advanced scarring and very thin corneas genuinely narrow the options. Often it reflects what was available to the person saying it, which for a long time was a real constraint: stabilize with cross-linking, fight with lenses, and when that stopped working, replace the cornea.
CTAK changes the shape of that conversation. A femtosecond laser sculpts sterilized donor corneal tissue to match your own corneal map, and that inlay is placed inside a channel in your cornea. Nothing is cut away. The cone is rounded back toward a more regular shape, which is usually what makes glasses and contacts workable again. Because no tissue is removed, a transplant remains available later rather than foreclosed.
McKinney is about twenty minutes down 121 or 75, and it is one of the service areas that refers to us most. Dr. Shehz is cornea-trained and performs cross-linking, CTAK, and keratoconus management at our Plano facility. Bring your topography printouts if you have them — the second opinion starts with reading your actual maps, not with a brochure.
CTAK adds tissue rather than removing it. That single fact is why it keeps your options open instead of spending them.
i.
We will tell you if it does not fit.
Significant central scarring or a cornea too thin rules CTAK out, and we say so plainly. A second opinion is only worth the drive if it is candid.
ii.
Your maps, read properly.
Bring prior topography. Comparing it against fresh imaging is how progression gets established, and progression is what determines urgency.
iii.
Nothing is removed.
CTAK is additive by design. It preserves the cornea you have — and with it, the choices you might want in ten years.
02/Beyond stabilizing
Keratoconus has three separate problems. Most clinics only treat one.
A cone-shaped cornea is progressive, it is irregular, and it is hard to correct. Those are three different problems. Cross-linking answers the first by halting progression. It does not answer the second — a stabilized cornea is still a distorted one.
CTAK answers the second. By adding laser-shaped donor tissue inside your own cornea, it works toward a more regular surface, which is what makes the third problem tractable: glasses and contacts start working again. Which combination your eye needs, and in what order, is what the consultation is for.
03/Treatment options
The pathway runs in order. Stabilize, reshape, refine.
Which of these your eye needs, and in what sequence, comes out of the corneal maps rather than off a menu. Cross-linking is the time-sensitive one. Reshaping can wait for a stable cornea, and usually should.
Reshape without a transplant
CTAK (Corneal Tissue Addition)
A piece of sterilized donor cornea, laser-shaped to the map of your own eye and placed inside your cornea to round the cone back toward its natural shape. Nothing is removed, so a transplant stays on the table rather than behind you.
The FDA-approved treatment that uses riboflavin and ultraviolet light to strengthen the collagen bonds holding your cornea's shape. It does not reverse keratoconus — it stops it getting worse, which is why timing matters more here than anywhere else.
Scleral and rigid gas-permeable lenses vault over an irregular cornea and give light a smooth surface to pass through. Often the bridge between diagnosis and stability — and, after CTAK, frequently easier to fit and wear.
Three steps, in this order. Skipping one is how people end up stuck.
Keratoconus care is a sequence, and the order is not arbitrary. Stabilizing a cornea that is still changing comes first, because reshaping one that has not settled does not hold. Each step below answers a different question about your eye.

Stop the progression
Corneal cross-linking strengthens the collagen bonds holding your cornea's shape. It is the time-sensitive step: it protects the cornea you still have rather than recovering the cornea you had.

Reshape the cone
CTAK places a laser-shaped piece of sterilized donor tissue inside your own cornea, working the cone back toward a regular shape. Nothing of yours is removed, which is what separates it from a transplant.

Sharpen what is left
Once the cornea is stable and more regular, glasses or specialty lenses do the remaining work — and a more regular cornea is markedly easier to fit and more comfortable to wear against.
04/Getting here
The drive is the easy part.
The route
South on US-75 or west along SH-121 — about twenty minutes from most of McKinney. Ground floor with free parking.
A second-opinion consultation runs about 60–90 minutes with full corneal mapping. Bring any prior topography, pachymetry, or operative notes — comparison against older imaging is often the most useful thing in the room.
Open Monday–Friday 8:00–5:00 and Saturday 9:00–3:00, with English- and Spanish-speaking staff. Questions before booking? Call 214-972-2020 and a human answers.

I was told I will eventually need a corneal transplant. Is that always true?
Not always. Advanced central scarring and very thin corneas do narrow the options, and we will tell you if that is your situation. But CTAK — adding laser-shaped donor tissue inside your own cornea — sits between cross-linking and transplant for many patients, and it did not exist as an option for much of the time that advice has been given.
Will CTAK mean I no longer need glasses or contacts?
Usually not, and that is by design. The goal is a cornea regular enough that glasses or contacts work well and comfortably again — restoring correctable, functional vision rather than eliminating correction.
What should I bring to a second opinion?
Any corneal topography or tomography printouts, pachymetry numbers, notes from prior cross-linking, and your current contact lens prescription. Comparing older maps against new imaging is how we establish whether the cornea is still changing.
Where does the donor tissue come from, and can my body reject it?
It is sterilized, processed donor corneal tissue prepared to strict standards. Because it is processed for sterility rather than transplanted as living tissue, the rejection risk is very low compared with a full corneal transplant.
Can I have CTAK if I have already had cross-linking?
Often yes. Many patients follow exactly that sequence — cross-linking to stabilize the cornea, then CTAK to reshape it. Your prior treatment records help us plan the timing.
How far is Plano from McKinney?
About twenty minutes on US-75 or SH-121. Ground floor, free parking.
Still have questions?
Talk to our team, no pressure, no sales pitch. We answer the question, not the upsell.
Between stabilizing and replacing, there is more than there used to be.
Cross-linking holds the line. Specialty lenses buy function. CTAK reshapes. A transplant remains the answer for some eyes — but it should be the conclusion of an evaluation, not its opening assumption.
Get the maps read again. Twenty minutes, and a straight answer.
Bring your topography. We will tell you what it actually shows, whether the cornea is still changing, and which of cross-linking, CTAK, or lenses fits your eye. About twenty minutes from McKinney. Call 214-972-2020 or book online.
